As much as we have grown used to seeing this message on
every kernel boot, it does not add any technical value.

Drop all messages from sdhci_drv_init().

We need to keep the module_init/exit() calls to stub
functions for the module to work according to
<linux/module.h>.

But is that true?

I don't know, I don't have an SDHCI device at hand to test..

The comments say:

/* Each module must use one module_init(). */

And for module_exit():

/* This is only required if you want to be unloadable. */

If it's not true we need to fix the docs as well...

But I discussed it with Ulf in the office last week and he was
frantically testing out dropping it altogether.

Yours,
